Please try the following:
function VWMA( array, period )
{
return Sum( array * V, period ) / Sum( V, period );
}
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( VWMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ),
ParamStyle("Style") );
NOTE: This TJ's Code.

Subject: [amibroker] Understanding Volume-Weighted Moving Average?
Hi guys,
I am trying to understand Volume Weighted Moving Average. The AFL seems
to be as follows (a 10-day example):
VWMA = Sum((Volume*Close),10) / Sum (Volume,10);
This looks like a regular MA. Does it make sense to use an EMA version
of this? What would the AFL look like for that?
Thanks as always for any help!
